Spraying brassinolide can change the growth habits of green onions, promote the growth of underground parts, prevent the stalks from being slender, increase leaf growth, make them grow stronger, and enhance their disease resistance and stress resistance.

Breaking seed dormancy,The optimum temperature for germination of lettuce seeds is 15-29℃. Above 25℃, the germination ability is significantly reduced under lightless conditions. Seeds that break dormancy can improve their germination ability under high temperatures. When the soil temperature reaches 27℃, lettuce seeds can usually be induced to dormant.
